Every commit that reaches the default branch must be signed; a ruleset refuses unsigned pushes. Estate policy: SIGNING-POLICY.
-
People and interactive agents sign with an SSH key registered on GitHub as a signing key (
gpg.format=ssh,user.signingkey=<key>.pub,commit.gpgsign=true). The committer email must be verified on that account. -
Apps, bots and workflows never
git pushlocal commits. They write through the API (createCommitOnBranchor the estatesigned-pushaction) so that GitHub signs each commit. -
Merge PRs with squash. The ruleset checks every commit on the PR branch, not just the result, so one unsigned commit blocks the merge. Re-create such a branch with signed commits (
git cherry-pick -S) and open a new PR. Rebase-merge replays commits unsigned and is disabled.
